Do you like how this looks?

Its an Animation Blueprint that uses spring controller for the chest so far it does work really well.

Should I do this to for any new mods that I make also which old mod do you want this to be added?

Can't say that I can make it for every game so far I have only tried it on two games.

Also how much should the chest move?
